In addition, the inner arm of the decorative cover is thickened to increase its force support and flexibility to resist deformation, which can better protect the door. In addition, the door lock decorative cover in the utility model is made of thermoplastic polyolefin (TPO) material, which enhances the tensile and deformation resistance of the decorative cover, and can better adapt to harsh environments such as high temperature and low temperature; the surface of the decorative cover is also smoother, and the overall visual sense of the decorative cover is better and more beautiful.

[0026] For example, Figure 1 A three-dimensional structural schematic diagram of a vehicle door lock decorative cover provided by an embodiment of the utility model. In the vehicle door lock decorative cover provided by the utility model:

[0027] Reference Figure 1 The door lock decorative cover includes: an annular outer arm 1, an annular inner arm 2, and a groove bottom plate 3.

[0028] The annular outer arm 1 includes three parts: a first limiting portion 11, a second limiting portion 12, and a first bending portion 13. The first limiting portion 11 and the second limiting portion 12 are both U-shaped structures, and the first bending portion 13 is located between the first limiting portion 11 and the second limiting portion 12. That is, the annular outer arm 1 is a bent annular structure as a whole, and is L-shaped when viewed from the side.

[0029] The annular inner arm 2 includes four parts, namely, a third limiting portion 21, a fourth limiting portion 22, a second bending portion 23, and a strip-shaped protrusion 24. The third limiting portion 21 and the fourth limiting portion 22 are both U-shaped structures, and the second bending portion 23 is located between the third limiting portion 21 and the fourth limiting portion 22. That is, the shape of the annular inner arm 2 except the strip-shaped protrusion 24 is the same as that of the annular outer arm 1, and is also a bent annular structure.

[0030] Optionally, the thickness of the annular outer arm 1 is smaller than the thickness of the annular inner arm 2, so as to increase the force support and flexibility of the annular inner arm 2 to resist deformation, thereby better protecting the vehicle door.

[0031] Optionally, the length of the first limiting portion 11 is smaller than that of the second limiting portion 12 , and the length of the third limiting portion 21 is smaller than that of the fourth limiting portion 22 , so that the shape of the decorative cover better fits the door lock.

[0032] The groove bottom plate 3 is arranged between the annular outer arm 1 and the annular inner arm 2 , and the curvature of the groove bottom plate 3 is the same as that of the annular outer arm 1 and the annular inner arm 2 .

[0033] Furthermore, the groove bottom plate 3 and the annular outer arm 1 and the annular inner arm 2 form a door lock limiting space. After the decorative cover is pressed and installed at the door lock, the sheet metal layer structure at the door lock is inserted into the door lock limiting space to fix the door lock decorative cover on the door lock.

[0034] In addition, there are a plurality of limiting grooves on the strip-shaped protrusion 24 . Moreover, the length of the strip-shaped protrusion 24 is smaller than the length of the fourth limiting portion 22 .

[0035] Exemplarily, the plurality of limiting grooves may include: two semicircular limiting grooves 241 and two arc-shaped limiting grooves 242 .

[0036] from Figure 1 It is not difficult to see that the semicircular limiting grooves 241 are located at both sides of the U-shaped bottom of the fourth limiting portion 22, and the arc-shaped limiting grooves 242 are located at the connection between the fourth limiting portion 22 and the second bending portion 23.

[0037] Therefore, a door lock limiting space is formed by the plurality of limiting grooves on the strip-shaped raised portion 24 , in cooperation with the groove bottom plate 3 , the annular outer arm 1 , and the annular inner arm 2 , which can achieve a better effect of fixing the decorative cover.

[0038] In one possible implementation, the door lock decorative cover is made of TPO material to enhance the decorative cover's resistance to stretching and deformation, so that it can better adapt to harsh environments such as high and low temperatures; the surface of the decorative cover is also smoother, and the overall visual effect of the decorative cover is better and more beautiful.

[0039] Based on the above technical solution, the utility model provides a door lock decorative cover, in which the inner and outer arms of the door lock decorative cover form an inner buckle structure, which can be reliably fixed at the door lock, and the overall curved shape is more in line with the shape of the door lock. After the door is closed, the door lock engagement hole can achieve a good sealing effect, preventing dust and foreign matter from entering the door from the door lock during the use of the car and causing negative impacts on the mechanical parts. In addition, the inner arm of the decorative cover is thickened to increase its force support and flexibility to resist deformation, which can better protect the door. In addition, the door lock decorative cover in the utility model is made of TPO material, which enhances the tensile and deformation resistance of the decorative cover, and can better adapt to harsh environments such as high temperature and low temperature; the surface of the decorative cover is also smoother, and the overall visual sense of the decorative cover is better and more beautiful.
